PDF Architect Pro Activation Problem

Hi,

I am from portugal and all the numbers are international so the call will be to expensive for me.

I received 1 email from purchase@upclick.com with the billing information and the activation key.
When i try to activate i get (translated from portuguese) “Check your internet connection Copy and paste you licence key to avoid mistakes If you are not able to activate or if you already used your license key pelase contact support.”

Thank you,
Regards.
